<p>A phase transformation heat exchange device (1) is provided with an inner tube (2), an outer tube (3) and a heat exchange medium (4). A liquid phase region is formed in all or part of the space between the two inner and outer tubes (2, 3). A vaporization region is formed in all or part of the space inside the inner tube (2). The heat exchange medium (4) of relatively high pressure inside the liquid phase region is heated in vortex flow and enters the vaporization region of relatively low pressure, and then, flows out of the phase transformation heat exchange device (1) after being vapored, thereby the heat exchange is completed. The device which can be applied to DSG systems of the solar photothermal field, and to an input-output system of a heat storage system or the field of heating with a boiler, is achieved with safe operation, low cost, and good application range.</p> |
